Whenever I open vim I get this error:
stty: illegal option -- --save
usage: stty [-a|-e|-g] [-f file] [options]
Then, when I quit I see:
stty: illegal option --
usage: stty [-a|-e|-g] [-f file] [options]

I’ve tried both iTerm and terminal. Also, this just randomly started happening it seems. I’m on VIM 7.3. Nothing appears to be wrong with vim, but I just get nasty output. Also, it’s nothing in my vimrc file. I removed the file to make sure and I still get the error.
sttyhas nothing to do with Vim. Check (or post) your .vimrc to see if it invokes, somehow,stty. Or check your*rcfiles, maybe.
